7.5 STOPPING
1. Throttle pump discharge to minimum flow.
Warning: do not close suction valve, this will cause the pump to run dry.
2. Turn the power off to the driver.
3. Close the pump discharge valve.
4. Observe the run-down of the pump until full stop.
If the rotor is jerky or suddenly stops, there is a danger that the rotor has become
blocked. The pump must be opened and all running clearances checked.
5. Close the suction valve when the pump shaft stops rotating as the pump must be isolated
before examination and made safe.
Do not close the suction valve until the pump has come to a full stop, as it may
cause the pump to run dry.
6. Ensure the drive motor cannot be unintentionally turned on.
7. Ensure the shut-off devices in the suction and pressure pipes cannot be unintentionally
opened.
8. Drain the pump and the auxiliary piping.
If the outside temperature is below 32 °F (0 °C), all cooling chambers must be
emptied, and all seal system cooling coils must be drained.
